Derek Frader and Dominic Frangella from East West Karate in Mesa share some HEF drills. (High Energy Finish) These drills are part of the Elements II cycle and used in the 5 minutes of class before the mat chat. Fun stuff and great drills to help students with proper execution of technique. https://www.youtube.com/watch?v=Bh4QhdraFBw&feature=youtu.be
